LEVER-POWER CHURN.

Specification of Letters Patent.

Patented April 21, 1908.

Application filed April 4, 1907. Serial No. 366,264.

To all whom it may concern:

Be it known that I, WILLIAM J. JoNEs, a citizen of the United States,residing at Martinsville, in the county of Henry and State of Virginia,have invented the Lever-Power Churn.

The invention relates to improvements in churns.

The object of the present invention is to improve the construction ofchurns, and to provide a simple and comparatively inexpensive onecapable of easy operation and of enabling butter to be rapidlyproduced.

With these and other objects in View, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawing, and pointed out in the claimshereto appended; it being understood that various changes in the form,proportion, size and minor details of construction, within the scope ofthe claims, may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the drawing :Figure 1 is a perspective view of a churn, constructedin accordance with this invention. Fig. 2 is a vertical sectional viewof the upper portion of the churn. Fig. 3 is a horizontal sectional viewon the line 33 of Fig. 2. Fig. 4 is a detail view of the nut.

Like numerals of reference designate corresponding parts in all thefigures of the drawing.

The supporting frame of the churn is composed of a lower churnbody-receiving portion and an upper guiding portion. The lower churnbody-receiving portion is provided with a horizontal base 1 and acorrespondingly shaped top 2, which is supported by corner posts 3. Thetop 2 of the lower portion of the frame is provided with a centralopening through which passes a stem 4 of a dasher 5. The dasher 5, whichmay be of any preferred construction, operates within a churn body 6,arranged upon'the base 1 of'the frame.

The upper guiding portion of the frame is composed of spaced uprights 7and inclined braces 8, located in advance and in rear of the uprightsand secured to the same at points between the ends thereof. The inclinedbraces 8 are mounted on the top 2 of the lower portion of the frame, andthe uprights are connected by a cross piece 9, located at a pointbetweenthe top andbottom cured by suitable fastening devices.

of the guide portion of the frame and forming a support for a nut 10.The transverse bar or support is bifurcated at its ends to receive theuprights, as clearly illustrated in Fig. 3 of the drawing. 7

The uprights are provided at their inner faces with vertical guides 11,consistin of spaced strips or flanges suitably secured to the innerfaces of the uprights and forming guiding grooves for the reception of avertically reciprocating slide or frame 12. The vertical reciprocatingslide or frame is composed of spaced sides, connected at their upperends by a substantially rectangular yoke 13, and at their lower ends bya bearing 14. The yoke 13 is composed of a horizontal bottom ortion 15and spaced sides having parallel ower portions to which the upper endsof the sides of the reciprocating frame are se- The upper portions ofthe sides of the yoke are bent inwardly, and their upper terminals areivoted to the lower end of a link 16. The l ower ends of the sides ofthe reciprocating frame are rovided with inwardly extending horizontalugs 17 to which the lower bearing 14 is secured.

The reciprocating frame carries a screw shaft 18, provided with spiralribs or flanges and having upper and lower journals or gudgoons 19 and20. The upper journal or gudgeon is reduced and is arranged in a bearingopening of the bottom 15 of the yoke, and is secured to the same by anut 19, or other suitable means, whereby the screw shaft is supported bythe yoke. The lower journal of the screw shaft is arranged in thebearing 14 and is provided at its lower end with a suitable socket 21 inwhich the upper end of the stem 4 of the dasher is secured. The screwshaft passes through the nut 10, which is provided with spiral groovescorresponding with the ribs or flanges of the screw shaft, whereby whenthe frame 12 is reciprocated the screw shaft will be reversely rotated.By this construction, the dasher is vertically reciprocated and isreversely rotated and is thereby enabled to rapidly effect theproduction of butter. The screw 10 is in the form of a sleeve and isprovided at the top with an annular attaching flange 22, which issecured by screws, or other suitable fastening devices to the support 9.

The link 16 is pivoted to a cuff 23, which is arranged on one end of anoperating lever 24. The cuff 23 is secured to the lever by a pin 25, orother suitable fastening device, and its sides are spaced a art at thebottom to receive the upper en of the link. The lever is fulcrumed at anintermediate point on a post 26 and is equipped with a suitable clamp orhandle 27 The post 26 is mounted upon the top 2 of the lower portion ofthe churn, and is arranged in rear of the guiding portion of the frame.The link connection between the lever and the slide or frame 12 enablesthe latter to be freely reciprocated by the operating lever.

I claim:

In a churn, the combination of vertical guides, a horizontally disposedfixed nut arranged between the guides at a point intermediate of theends thereof and supported by the same, an upper yoke, slidable parallelbars secured at their upper ends to the sides of the yoke and movable inthe guides, a lower bearing secured to the lower ends of the bars andspacing the same, a screw swiveled at its upper end in the yoke andjournaled at its lower end in the said bearing and passing through theintermediate nut, a hand lever connected with the yoke, and a dasherconnected with the lower end of the screw.

WILLIAM J. JONES.
